Abstract
Denne afhandling undersøger, om smartphones kan øge fysisk aktivitet blandt kontoransatte ved hjælp af Just-In-Time Adaptive Interventions (JITAI). I samarbejde med en afdeling hos Novo Nordisk A/S blev JITAI Walk udviklet og afprøvet i et realistisk arbejdsmiljø med 21 medarbejdere. Interventionen bestod af en mobilapplikation, der leverede aktivitetsnotifikationer, når bestemte betingelser var opfyldt, med udgangspunkt i JITAI-principper om tilpasning, beslutningsregler og skræddersyede tidspunkter. Metodisk omfattede studiet både kvantitative analyser af aktivitetsdata og kvalitative vurderinger af appens brugervenlighed og oplevet påvirkning af produktivitet. Resultaterne viste, at JITAI Walk gjorde det muligt at øge den fysiske aktivitet i arbejdstiden, samtidig med at notifikationerne øgede medarbejdernes opmærksomhed på deres aktivitetsniveau og vigtigheden af at være fysisk aktive i løbet af dagen. Afhandlingen peger på, at designet af appens notifikationer er en central komponent for effekt og accept, og at JITAI-tilgangen er gennemførlig i en kontorarbejdskontekst uden for laboratoriet.
This thesis examines whether smartphones can increase physical activity among office workers using Just-In-Time Adaptive Interventions (JITAI). In collaboration with a department at Novo Nordisk A/S, the JITAI Walk intervention was designed and tested in a real-world workplace with 21 employees. The intervention centered on a mobile application that delivered activity notifications when specified conditions were met, applying JITAI principles of tailoring, decision rules, and timely prompts. The study employed both quantitative analyses of activity data and qualitative assessments of app usability and perceived impact on productivity. Findings indicate that JITAI Walk made it possible to increase physical activity during working hours, while notifications heightened users’ awareness of their activity levels and the importance of being active throughout the day. The work underscores the importance of notification design for effectiveness and acceptance and demonstrates the feasibility of a JITAI approach in office settings outside laboratory conditions.
